3.13.11.7 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Sasha Levin <[email protected]> commit 618fde872163e782183ce574c77f1123e2be8887 upstream. The rarely-executed memry-allocation-failed callback path generates a WARN_ON_ONCE() when smp_call_function_single() succeeds. Presumably it's supposed to warn on failures.
